Definitions

  • This invention relates to a golf club that has adjustable loft settings.
  • a head set at a steep angle causes a golf ball to fly through a steeper and shorter trajectory than a club where the head is at a lessor angle (eg 10°).
  • the adjustability means that one club can be used to give the same loft range as several clubs.
  • a golf club or part thereof comprising:
  • biasing means that provides a locking force that seeks to move the head and hosel apart and, in doing so, causes the head to remain locked in one or other of a selection of loft settings; the golf club or part thereof being such that hand force can be applied to move the head inwards to overcome the locking force to free the head to be turned into another of the loft settings, and such that subsequent reverse movement of the head will cause it to be locked in that other setting; wherein the head has a series of locking teeth and the hosel has a series of locking teeth, these being arranged such that they intermesh to lock the head in any of the loft settings and subsequently disengage when the head has been moved by hand to overcome the locking force to enable the head to be turned to another of the loft settings; and the two series of locking teeth are in a male-female engagement wherein the teeth of the hosel are male and the teeth of the head are female, and each set of teeth is substantially conical and tapers outwards in the direction of the toe end of the club or part thereof.
  • the locking force bias drives the head outwards to cause the head to be locked in said other setting.
  • the biasing force is provided by a spring.
  • the spring is arranged around the shank.
  • the locking teeth of the head and the hosel each comprise a set of radially longitudinally extending teeth.
  • the hosel’s set of teeth sleeve-fit into, and mesh with, the head’s set of teeth when the head is locked in any one of the loft settings.
  • a nut fitted to a toe end of the shank, a retainer secured to the shank by the nut, and the retainer being in butting relationship with the head when the head is locked in one of the loft settings so that the head cannot be pulled free of the shank.
  • the butting relationship is between the retainer and a liner forming part of the head.
  • the liner is releasably screw-fitted to another part of the head.
  • a golf club comprising:
  • a hosel having a cone shaped series of locking teeth arranged such that each of these teeth extend in a straight line, and a shank that extends along at least part of, and that engages with, the head;
  • biasing means that provides a spring locking force that seeks to move the head and hosel apart and, in doing so, causes the head to remain locked in one or other of a selection of loft settings; the two series of locking teeth being arranged such that the cone shape of one sleeve-fits into the cone shape of the other in a meshed male-female relationship to lock them against rotation, but wherein hand force can be applied to move the head inwards to free the head to be turned into another of the loft settings, and such that subsequent reverse movement of the head will cause it to be locked in that other setting.
  • a golf club or part therefor comprising: a) a ball-strike head; b) a hosel; and c) slip gears; the club or part therefor being formed such that: o the head and the hosel engage one another to releasably lock the head in one of a plurality of loft settings; o spring force acts on the slip gears to bias the teeth of one slip gear to engage with teeth of another; o hand force can be applied to the head to rotate it into another of the loft settings to be locked in that other loft setting; and o as the head is rotated into said other loft setting at least one of the slip gears rides over another of them to generate a click sound and/or a tactile indication to give a person adjusting the club audible and/or tactile feedback of the adjustment.
  • the ball-strike head is integral with or secured to a first locking gear comprising splines; b) the hosel is integral with or secured to a second locking gear comprising splines; c) spring force acts on the locking gears to bias them to engage one another; d) hand force can be applied to the head to move it towards the heel of the club against the bias on the locking gears to unlock the head so that it can be hand rotated into the other of the loft settings and then released such that the same bias causes the head to be locked in that other loft setting.
  • the spring force that acts on the male and female gears and the spring force that acts on the slip gears is provided by a common spring.
  • the common spring is compressed to assert a force that urges the head away from the heel of the club and, at the same time, urges at least one of the slip gears to engage another.
  • the spring force acting on the locking gears is provided by a first spring, and the spring force acting on the slip gears is provided by a second spring.
  • the first spring provides substantially less force than the second spring.
  • first and second springs comprise elongate coils that are arranged substantially in line with one another.
  • a central portion of the first spring has nothing supportive extending through it (eg it is not associated with an internally arranged shaft or the like).
  • slip gears comprise an inner slip gear, a medial slip gear and an outer slip gear, the click sound being generated when teeth of one or other of the inner and outer slip gears clash with teeth of the medial slip gear.
  • the first locking gear is a female gear and its splines run in a longitudinally tapered configuration and the taper extends from narrower to wider as it proceeds towards the toe end of the club; and b) the second locking gear is a male gear and its splines also run in a longitudinally tapered configuration and the taper extends from narrower to wider as it proceeds towards the toe end of the club.
  • one of the slip gears is unable to rotate.
  • the first locking gear engages the shaft at the heel end of the club.
  • the second locking gear is secured inside, or is integral with the inside, of the head.
  • slip gears are adjacent to the toe end of the club.
  • each slip gear has the same number of gear teeth as each of the first locking and second locking gears.
  • slip gears are coordinated with the first and second locking gears such that rotation of the head into the other loft setting produces only one audible click per change in loft setting.
  • slip gears are coordinated with the first and second locking gears such that rotation of the head into the other loft setting produces one tactile bump that corresponds with the audible click.
  • the loft settings there are more than two of the loft settings and the loft of the head can be adjusted by rotating it to each setting in turn in the same way.
  • the tactile indicator is a bump or vibration that can be felt by the person when the slip gear rides over the other slip gear.

  • FIGS 2 & 3 show some components of the club prior to assembly.
  • the hosel 2 has a cylindrical shank 5 arranged to extend into a space inside the head 1 and connect to a nut 6 at the toe end of the head.
  • the distal end of the shank has a male screw thread 7 and the nut has a complimentary female thread 8.
  • the arrangement is such that shank 5 passes through a spring 9 inside the head 1 , and the nut 6 sits inside a complimentary shaped retainer 10.
  • a spacer 22 may be used to configure the compression tension that the spring is under.
  • a cylindrical weight 11 is arranged to sit snugly but removably in a further space inside the head and is held there by a grub screw 12. The weight 11 is to help ‘balance’ the club and can be replaced by a heavier or lighter similar weight to suit the person using the club.
  • the retainer 10 sits inside a sleeve 1c that may be considered to be part of the head 1 (in this example the sleeve 1c is screw-fitted to the rest of the head 1).
  • the arrangement is such that the spring 9 is under compression to provide a force that seeks to urge the head 1 outwards away from the heel end of the club.
  • the head 1 and hosel 2 are not able to separate because a contact surface 13 of the liner 1c butts against a complimentary contact surface 14 of the retainer 10. In other words the spring 9 is unable to move the head outwards beyond the shank 6 and retainer 10.
  • FIG 4a shows the exterior of the head 1 and hosel 2 when in the Figure 4 disposition.
  • An axial retainer or circlip 23 may be used to assist in in securing male teeth 17 (see Figure 2).
  • Figure 5 illustrates the same components as Figure 4, but when the head 1 has been pushed inwards by hand towards the heel of the club (i.e. to the right in the drawing) to compact and overcome the biasing force of the spring 9. This is done to release the club for adjusting the angle between the head and hosel.
  • What the movement does is cause complimentary male 17 and female 18 conical or otherwise tapered ‘fin-like’ or ‘spline’ teeth internal to the heel end of the head to disengage (the male teeth 17 are an integral or connected part of the hosel 2 and the female teeth 18 are an integral or connected part of the head 1).
  • the teeth 17 and 18 may be considered ‘conical’ in that they run in straight lines to generally provide the periphery of a cone shape.
  • the mail teeth 17 may be secured to the shank 5 using a circlip (see Figure 2).
  • the disengagement of the teeth 17, 18 enables the head to be turned with respect to the hosel by hand. This has the effect of changing from one to another of the loft settings 4 (the settings are shown in Figure 1).
  • the spring pushes the head back to the Figure 4 arrangement so that the teeth 17, 18 reengage to lock the head in the new loft setting.
  • the arrangement is generally that of a smaller conical set of teeth 17 fitting into a larger conical set of teeth 18.
  • Figure 5a shows the exterior of the hosel and club head when in the Figure 5 disposition.
  • Figure 6 & 6a illustrates detail of the hosel 2.
  • An index line 19 enables the correct alignment of various loft settings 4, which can also be seen in Figure 1.
  • the heel end of the hosel has a series of radial slip teeth 20 extending outwards, behind and spaced from the locking teeth 17. These slip teeth 20 are arranged to engage with complimentary radial slip teeth of the head. While the two sets of slip teeth are meshed/engaged, when the head is turned into or out of one of the loft settings 4 they are able to ride over one another and, as a consequence, the person turning the head hears ‘clicks’ and feel bumps as they clash. This gives the user a nice audible and ‘tactile’ impression during loft adjustments.
  • Figure 6a illustrates an example of an anti-rotation feature in the hosel, being keys 24 at the beginning of the shank, arranged so that the male splines 17 cannot rotate relative to the hosel.

  • Figure 8 illustrates the female teeth 18 connected to the rest of the head 1.
  • the teeth may be formed as an integral part of the head.
  • FIG. 9 illustrates an alternative embodiment of a loft adjustable golf club according to the invention.
  • the club has a ball striking head 1 , a hosel 2 and a shaft 3.
  • the upper end of the shaft 3 serves as a handle for swinging the club.
  • the hosel incorporates a cylindrical shank 5 that receives a cone-like set of longitudinally tapered male teeth 17.
  • the arrangement is such that the interior of the male teeth 17 have slots that are complimentary with and engage keys 24 forming part of the shank 5.
  • the keys 24 prevent the male teeth 17 from rotating with respect to the shaft 5.
  • the drawing does not show the equivalent of the tapered female teeth 18 described previously because in this instance they are within the head.
  • the mechanism includes a tube 25 through which the shank 5 passes inside the head 1.
  • the heel end of the tube has a ledge 26.
  • the arrangement is such that spring 9 extends around the narrow portion of the tube 25 but is not able to push past the ledge 26.
  • the ledge 26 also contacts and prevents longitudinal movement, or in other words prevents axial movement, of the male teeth 17.
  • the toe end of the tube 25 passes through an inner slip cog 27.
  • the slip cog 27 is able to slide longitudinally with respect to the tube 25, but cannot rotate around it.
  • a further feature of the slip cog 27 is that it has a ring of slip teeth 28 facing the toe end of the club. These engage with a complimentary inward facing ring of slip teeth 29 of an outer slip cog 30. This outer slip cog 30 moves axially with the head, and turns with the head when the head is rotated.
  • a barrel nut 6 is threaded to screw fit onto the distil end of the shaft 5 and tightens against a slider 31 , which in turn presses against the tube 25.
  • the arrangement is such that the slider 31 is trapped between the nut 6 and the tube 25.
  • the slider 31 has grooves 32 which enable the inner slip cog 27 to move axially but not rotate.
  • a retainer 33 is thread-fitted into the outer slip cog 30 to hold it in place.
  • Figures 10a and 10b show the Figure 9 mechanism when assembled and with both sets of slip teeth 28, 29 interlocked. They are urged together by way by pressure from the spring 9 which is under compression.
  • the head 1 When it is desired to adjust the loft of the club, the head 1 is moved towards the heel end of the club as before, to disengage the tapered sets of teeth 17, 18, so that the head can be rotated about the shaft 5 to bring the head into a different one of its loft settings.
  • the movement from the locked to the unlocked positions is illustrated in Figures 11a and 11b respectively.
  • the club head 1 When unlocked, the club head 1 is rotated by hand into the new loft setting. As this occurs, the slip teeth 28, 29 ride over one another as illustrated at Figures 12a and 12b and, as this occurs, they cause audible clicks and vibratory or bumping movements corresponding with each clash of teeth. This gives the person adjusting the club both audible and tactile feedback, which enhances the marketability and perceived quality of the club.
  • Embodiment 3 Embodiment 3
  • Figure 13 illustrates a further alternative embodiment of the invention. It is largely similar to Embodiment 2 described above, and for that reason more or less equivalent parts have been given the same reference numbers. Substantially the only difference to Embodiment 2 is that in Embodiment 3 the inner slip cog 27 is shorter and there is no slider 31. The tube 25 prevents axial movement of the inner slip cog 27. And the spring 9 is, again, always in compression and has one end in contact with the outer slip cog 30 and its other end in contact with the retainer 33. Also again, the inner slip cog 27 is unable to rotate or slide with respect to the tube 15.
  • the outer slip cog 30 can move axially inside the head 1 , cannot rotate relative to the head, and is pressed against the inner slip cog 27 by the spring 9.
  • Figures 14a and 14b show Embodiment 3 when the male and female teeth 17, 18 are locked and unlocked respectively.
  • Figures 15a and 15b illustrate how the slip teeth 28, 29 ride over one another to product clicking a sound and tactile bumps in the same way described above.
  • Figures 16 and 17 illustrate a loft adjustable golf club that represents a further alternative embodiment of the invention. For the most part substantially similar parts to those mentioned have been given the same reference numbers.
  • the club has a head 1 , a hosel 2 and a handle 3.
  • the hosel 2 incorporates a shortened shaft 5.
  • a set of conical male locking teeth 17 are supported on the shaft 5, and are adapted to engage a complimentary conical set of female locking teeth 18 that are integral with an internal part of the head 1 .
  • these sets of teeth 17, 18 each taper from a narrower end nearest the heel of the club to a wider end nearer the toe end of the club.
  • the head 1 can be moved by hand axially towards the heel of the club to disengage the teeth 17, 18 so that the head can be partly rotated to adjust it into one of several available loft settings.
  • the teeth 17, 18 automatically engage one another under spring tension to lock the club in the respective loft setting.
  • This tension is provided by a spring 9 that works to urge the female teeth 18 against the taper, or bank, of the male teeth 17.
  • the central portion of the spring 9 has nothing supportive extending through it (eg it has no central supportive shaft or the like). Because of the compression in the spring 9, the natural inclination of the head is 1 to pull away from the hosel, but it cannot because the narrow heel end of the female teeth 18 cannot slide past the widening taper of the male teeth 17. Again, this lock is enhanced by centripetal force when the club is swung to hit a golf ball in the normal way.
  • the spring 9 is located at the toe end of the club on a retainer 33 that is screw fitted to the head 1.
  • the other end of the spring is located against a top hat shaped thrust pad 34, that in turn engages the distil end of a barrel nut 35.
  • the other end of the barrel nut 35 is screw threaded around the shank 5 to fasten them to one another.
  • a second spring 37 is coiled around the barrel nut and maintained under compression between an arrangement of slip cogs at the heel end, and a washer 36 at the barrel nut. As shown, the washer 36 locates against the side of the barrel nut nearest the heel end of the club.
  • the arrangement of slip cogs comprises an inner slip cog 27 and an outer slip cog 30, which together sandwich a medial floating slip cog 38.
  • the inner slip cog 27 buts against the set of male teeth 17 and the outer slip cog 30 buts against the second spring 37.
  • the floating slip cog 18 has a series of radial right-angled teeth at each side to engage, respectively, with complementary shaped teeth of the inner and outer slip cogs.
  • the three slip cogs are constantly held against one another by pressure from the second spring 37. This means that they stay engaged even when the head 1 is moved axially towards the heel end of the club for adjusting the loft setting.
  • the second spring 37 preferably provides a significantly stronger tension than the other spring 9. However this does not hamper the axial movement of the head for loft adjustment, that is because a golfer only needs to overcome the lessor tension of the spring 9 to do this.
  • the teeth of the slips cogs ride over one another so that the golfer hears one click sound and also feels one bump, for each level of adjustment. For example if the golfer hears two clicks and feels two bumps, they know they have adjusted the club by two loft settings, such as from say a 7-iron setting to a 9-iron setting. This means that golfers with limited vision (eg those who normally need reading glasses) can know what loft setting they have the club in without having to view its marker scale. Of course as the teeth ride over one another they work against the tension of the second spring 9.
  • each of the inner and outer slip cogs is ratchet-like, in that they can each only rotate in one direction.
  • Figures 19A-C illustrate the clashing of the various different slip cog teeth depending on the direction of rotation.
  • Figure 20 illustrates, in side-view, the embodiment of Figures 16-19 when the club head 1 is locked in a loft setting.
  • Figure 21 shows the same arrangement of parts but when the head 1 has been moved axially towards to the heel end of the club to unlock the teeth 17, 18 for rotationally adjusting the loft of the club.
  • the outer slip cog 30 has a pair of diametrically opposed anti-rattle teeth 39.
  • these teeth 39 are located in complimentary slots 40 in the head. The engagement serves to arrest rattle between the head and the hosel as loft adjustment occurs. Flowever when the loft has been set and the club is ready to use, the teeth 39 are each free of their respective slot 40.
  • Figure 27 illustrates an arrangement similar to that of Figure 16 and 17, except it does not involve a floating slip cog 38.
  • the teeth of the inner 27 and outer 30 slip cogs may ride over one another to cause the clicking and bumps noticed by the golfer during loft adjustment.
  • the teeth are not shaped to ratchet, but rather they can ride over one another in either direction of rotation.
  • Figures 28 and 29 illustrate a loft adjustable golf club that represents a further embodiment of the invention. Parts that are substantially similar to those mentioned have previously been given the same reference numbers.
  • the club has a head 1 , hosel 2 and handle 3 as before. It also has conical set of male teeth 17 and a complementary conical set of female 18. These function in the manner described above, to releasably lock the club in whatever loft angle it has been set to.
  • the male teeth are preferably integral with the hosel, and the hosel has no shaft.
  • the spring 9 that biases the sets of teeth 17, 18 to a locked position sits around a stump 41 of the set of male teeth at one end, and around a stump 42 of the retainer 33 at the toe end of the head.

But when the club head is moved by hand axially towards the heel end of the club, the teeth 17, 18 are released so that the head 1 can be moved in a rotational manner to change the club’s loft setting.

Abstract

L'invention concerne un bâton de golf ou une partie de celui-ci. Il peut comprendre une tête de frappe de balle (1), un col (2) ayant une tige (5) qui s'étend le long d'au moins une partie de la tête et qui vient en prise avec ladite tête, un moyen de sollicitation (par exemple, un ressort (9)) qui fournit une force de verrouillage qui cherche à éloigner la tête (1) du col (2) et, ce faisant, amène la tête à rester verrouillée dans une des sélections des réglages d'angle d'ouverture (4).
